Pin function
Pin No. Pin name Pin function Equivalent Circuit
1 VCC Power-supply voltage pin.
VCC voltage is impressed. The permissible operation voltage is from
4.0 to 16.0(V). The capacitor is connected for stabilization for GND pin
(6pin).
2 IN1 Motor drive control input pin.
Driving control input pin of OUT1 (10pin) and OUT2 (9pin). It is used in
combination with IN2 pin (3pin). For the digital input, range of the "L"
level is 0 to 0.7(V), range of the "H" level is from 1.8 to 5.5(V). PWM can
be input. Pull-down resistance 100(k) is built into in the pin. It becomes
a standby mode because all IN1, IN2, IN3, and IN4 pins are made "L",
and the circuit current can be adjusted to 0.
3 IN2 Motor drive control input pin.
Driving control input pin of OUT1 (10pin) and OUT2 (9pin). It is used in
combination with IN1 pin (2pin). PWM can be input. With built-in
pull-down resistance.
4 IN3 Motor drive control input pin.
Driving control input pin of OUT3 (8pin) and OUT4 (7pin). It is used in
combination with IN4 pin (5pin). PWM can be input. With built-in
pull-down resistance.
5 IN4 Motor drive control input pin.
Driving control input pin of OUT3 (8pin) and OUT4 (7pin). It is used in
combination with IN3 pin (4pin). PWM can be input. With built-in
pull-down resistance.
6 GND Ground pin.
7 OUT4 Driving output pin.
The motor coil is connected between terminal OUT3 (8pin).
8 OUT3 Driving output pin.
The motor coil is connected between terminal OUT4 (7pin).
9 OUT2 Driving output pin.
The motor coil is connected between terminal OUT1 (10pin).
10 OUT1 Driving output pin.
The motor coil is connected between terminal OUT2 (9pin).

2. About the switch time from the stand-by state to the state of operation
When IN1, IN2, IN3, IN4 are "L", this IC has completely stopped operating. After the time of reset of about 7s of an
internal setting, it shifts to a prescribed output status corresponding to the state of the input when the signal enters the
input terminal.
Reset of about 7s doesn't hang even if the motor is driven from the stand-by state when either CH drives and the output
becomes an output status corresponding to the state of the input. As for full power TR between the reset time, turning
off is maintained.
3. Example of current wave type in each excitation mode when stepper motor parallel input is controlled.
Full-step mode Half-step mode
4. Thermal shutdown function
The thermal shutdown circuit is incorporated and the output is turned off when junction temperature Tj exceeds 180°C.
As the temperature falls by hysteresis, the output turned on again (automatic restoration).
The thermal shutdown circuit does not guarantee the protection of the final product because it operates when the
temperature exceed the junction temperature of Tjmax=150°C.
TSD = 180°C (typ)
ΔTSD = 40°C (typ)

Application Circuit Example
1. Example of applied circuit when two DC motor driving 2. Example of applied circuit when one stepper motor driving
3. Example of applied circuit when connecting it in parallel
The use likened to H bridge 1ch is shown possible in the figure below by connecting IN1 with IN3, IN2 with IN4,
OUT1 with OUT3, OUT2, and OUT4. (IO max=2.0A, Upper and lower total RON=0.5)
* Bypass capacitor (C1) connected between VCC-GND of all examples of applied circuit recommends the electric field
capacitor of 0.1A to 10A.
Confirm there is no problem in operation in the state of the motor load including the temperature property about the
value of the capacitor.
Mount the position where the capacitor is mounted on nearest IC.
